Cadillac will deliver a sporting luxury coupe with Chevrolet Volt-based technology for 2014. Called the ELR, the Caddy was previewed with the Converj concept at the 2009 Detroit auto show. These spy shots clearly reveal Caddy emblems and styling cues. Expect pricing to be elevated over the Volt. The ELR will run a more advanced T-shaped lithium-ion battery pack and four-cylinder engine. It gets a 2+2 seating configuration and will be revealed at a 2013 auto show.
